As long as both the frame and the transmission plate aren't too flexible and have a small amount of "loose" tolerance, there shouldn't be any problems. Team 228 had a similar design last year, taking the guts out of the Toughbox (except with a 12t CIM pinion gear instead of the 14t) and building it into the chassis with the output shaft of the gearbox direct driving the rear wheels of the robot. Our main competition robot used a single 0.125" CNC sheet metal plate without standoffs for the transmission, and the practice robot used a 0.1875" CNC-milled aluminum plate with standoffs. Both performed equally well, with the competition robot running an entire season (six competitions) and countless hours on the practice robot without any problems. Here's some photos:
